exhaust manifold
Hi,
Does anybody know if the exhaust manifold of a 85 Trans Am is the same on the lg4 version as on the TPI and HO version. Im thinking of using the exhaust Y-pipe from the TPI or HO on my lg4, since it is 3" instead of 2,5".

Im pretty sure the manifold on a l98 car are higher flow. However Im not sure if the y pipes are interchangable or not tho.
